Related Product Information for CD48 active protein

CD48 is a glycosylphosphatidylinositol -anchored protein belonging to the CD2 subfamily. It is expressed mainly on hematopoietic cells and exists in both membrane- associated and soluble forms. It is a low-affinity ligand for CD2 and is implicated as an important costimulatory molecule in lymphocyte activation. Indeed, CD48 has been described as facilitating cell adhesion, innate responses to bacterial infection, and graft rejection. In addition, CD48 is a high- affinity ligand for 2B4. CD48-2B4 interactions can modulate T cell, B cell, and natural killer (NK) cell functions and cross-talk.The absence of functional 2B4- CD48 interactions impairs NK cell cytotoxic response and IFN- release on tumor target exposure. Furthermore, activated NK cells significantly increase the CD3-dependent proliferation of CD8+ and CD4+ T cells by a 2B4-CD48-dependent mechanism.
